Abstract :
The concept and results of a new optimised synchronised discrete delta modulation (SDDM) scheme suitable for DC-AC power conversion in uninterruptible power supply (UPS) applications are presented. Unlike the traditional delta modulation scheme, the SDDM scheme has a well defined harmonic spectrum, resulting in simple filter design and reduced radio interference
